US 2002/0176393 A1 · Reduction in circuit scale of RAKE receiver in CDMA communication system

Abstract

A RAKE receiver according to the present invention has a chip rate finger processing unit for despreading received data and performing symbol integration for the received data, and a symbol rate finger processing unit for estimating propagation paths through which the received data has passed, and compensating the received data for the propagation paths. The RAKE receiver further has a number of chip rate finger processing units corresponding to the number of fingers, and symbol rate finger processing unit for the plurality of chip rate finger processing units. The symbol rate finger processing unit compensates each of received data delivered from the plurality of chip rate finger processing units for an associated propagation path, and combines received data sharing a common multiplexed code with one another for each multiplexed code.

A RAKE receiver comprising:

chip rate finger processing means including code generator means for generating a code for received data, despreading means for despreading said received data using the code generated by said code generating means, and symbol integrating means for performing symbol integration for said received data despread by said despreading means;
and
symbol rate finger processing means including propagation path estimating means for estimating propagation paths through which said received data has passed, and propagation path compensating means for compensating said received data, subjected to the symbol integration in said symbol integrating means, for the propagation paths based on the result of propagation path estimation in said propagation path estimating means.
